Referring tothe drawings 1 designates the Wagon body or receptacle forthe load, said body being of inverted frusto-pyramidal shape,contracting on all sides from the top to the bottom, or in other wordsal1 sides of the body converging toward the .bottom and being connectedto a bottom frame 2 divided centrally into two substantially equalrectangular discharge outlets by means of a division strip 3 extendingtransversely across said frame as shown in Fig. 9, Each of the outletopenings 4 of the bottom frame is adapted to be covered/anc"L uncoveredby one of a pair of slidable trap doors 5 each of which is slidable inrabbets 6 formed in the inner and lower corners of the longitudinal sidebars of the frame 2, the doors 5 loeing retained in place by means ofguiding strlps 7 secured to frame as shown in Fig. 17. Each of the doors5 has fixedly secured thereto a rack bar 8 toothed on its under face asshown at 9 and provided with a laterally extending pin 10 and a terminaleye 11 the pur ose of which will hereinafter appear. The ivision strip 3is provided with a depending eye 12 the function of which willhereinafter be e explained.

The body 1 rests upon and is directly supported by a foundation board 13which is illustrated in detail in Figs. 10 to 13 inclusive. Saidfoundation with an elongated central openin 14 and is movable up anddown with the iody 1 by means to bedescribed. The truck frame as shownin Fig. 1, comprises a top platform 15 and a bottom platform 16 and theend portions of the truck frame are in the form of boxed-in compartments17 and 18 leaving an intervening dispensing compartment or space 19directly below the discharge outlets of the body 1. Extending upwardlyfrom the top platform 15 are front and rear end uprights or standards 20in which are journaled top and bottom pulleys 21 and 22 respectively andaround said'lp-ulleys pass body raising and lowering flexibleconnections 23 shown in the form of chains, said chains being connectedat one end to the board13 and being connected at their opposite ends tochain winding shafts 24 which are geared to a common countershaft 25 inturn geared to a cross shaft 26 adapted to be driven-by a motor (notshown) mounted on the bottom face of the Y board is formed in (place bya cover Lasagne gear 31 thereon which meshes with and is driven by apinion 32 on a short shaft pro- ,vided with an operating hand crank 33.

The means just described provides for raising and lowering the body 1 byhand, while the operator is standing on the ground beside the wagon.

Asshown in Figs. 2 and 10, the foundation board 10 is provided at theopposite ends thereof with guiding lugs or ribs 34 and the standards oruprlghts 20 are provided on their inner faces with guiding ribs 35 whichare engaged by the lugs or ribs 34 of the foundation board as the latteris raised and lowered. The ribs 35 and lugs 34 are arranged to leave anintervening space. or channel 36 for the chains 23 as shown in Fig. 2.

The means for opening the bottom doors 5, comprises a pair of shafts 37extending transversely of the foundation board 13 as shown in Figs. 10and 11, said shafts 37 carrying pinions 38 which mesh with the teeth 9of the rack bars 8 shown in Fig. 9. On their opposite ends, the shafts37 have hand wheels 39 (see Fig. 10 thus enabling the doors 5 to beopened rom two points on each side of the machine. The shafts 37 arejournaled in bearings in the foundation board 13 and in addition to thepinions 38, they are provided with other pinions 40 one of which mesheswith a reverse motion pinion 41 (see Fig. 11). One of the pinions 40 andthe pinion 41, mesh with slidable rack bars 42 working in grooves 43 inthe bottom of the foundation board 13 as indicated in Figs. 11 and 12,the rack bars 42 being held strip 44 Secured to the er side of thefoundation board.

The means for operating the'bottom doors from the drivers seat,comprises cables 43 which are terminally attached to the rack bars 42 asshown in Fig. 10. Said `cables 43 extend around pulleys 45 (see Fig. 11)and upwardly around other pulleys 46 (see Fig. 7) to a pair of handlevers 47 and 48 mounted on a stud shaft 49 projecting from lthe frontend of the body 1 as shown in Figs. 7 and 19. Each of said leverscarries a ratchet wheel 50 adapted to be engaged by one of a pair ofdetents 51 on the body 1, and one of said levers islonger than the otheras shown in Figs; 7 and 19, each lever being terminallyprovided with ahand gri 52. This enables either lever to be operated independently ofthe other or both levers simultaneously. As a' result the ontlet doors 5may be operated simultaneously or independently and this is accomplishedby the driver without leaving his compartment. The front and rear endsof the body 1 are sustained by skeleton end supports which extend fromthe foundation board 13 upwardly to the top sill of the body l below the-bottoms of the loading doors herein after described.

Another means for operating the outlet doors 5 consists of flexiblecables 56 terminally attached to the eyes 11 of the rack bars 8andpassing around pulleys 57 on the foundation board 13 as shown in Fig.5 Where they are provided with terminal hand grips 58. This enables theoperator while standing on the ground to operate the outlet doorswhether the body is elevated or lowered.

The means for closing the outlet doors 5 embodies, as shown in Figs. 1and 5, a

pair of thrust arms 59 each pivotally mount` ed at 60 on the body 1 andhaving acurved portion 61 formed with an arcuate slot 62 which engagesthe pin 10 of the adjacent rack bar 8 as shown in Fig. 5. A contractilespring 63 connects each arm 59 with the body 1 and serves by means ofthe arm 59 to press the respective door 5 toward its closed positionafter the door opening means have been relaxed. Each of the thrust arms59 carries a detent 64 to engage a rack face 65 on the body 1 when itisdesired to hold the doors 5 open for a considerable period of time, aswhen discharging the entire load in one operation.

66 designates a double chute substantially triangular in cross sectionand comprising two chute-ways 67 divided from each other by thepartition 68 to the edge of which is attached a swivel hook 69 which isremovably fitted in the eye 12 of the bottom frame 2. The chute 66 alsocarries other swivel eyes 70 adapted to engage one of a pair of chutesupporting rails 71z one of which is illustrated in the detail view Fig.14. The construction of the hooks 69 and 70 is' illustrated in detail inFig. 1.5,. It will be apparent that the chute 66 may be reversed so asto discharge toward either side ot' the dump wagon and by having twocompartments, the discharge may be made through either of saidcompartments or simultaneously through both according to then'ianipulalion of the outlet doors 5. The chute 66 is also provided withshort coupling chains T2 to allow an extension chute 73 to be attachedto the chute 66. The main body of the chute 73 is illustrated asnarrower than the double chute 66 but is Vprovided with a flaredreceiving portion 74 to embrace both compartments of the double chute 66and the chute 73 is provided with attaching hooks 75 to engage thechains 72, thus en` abling the chute and the extension chute to bereadily associated and disconnected. As indicated in Figs. 1 and 5, thechute 66 is disposed in the dispensing compartment 19 of the truckframe. This enables bags, buckets or other receptacles to be placed onthe bottom platform 16 so that the may be individually filled by openingeit er one on both of the bottom outlet doors 5. Fig. 8 indicates thetwo reverse positions of the chute 66 by full and dotted lines, also themanner of supporting said chute in relation to the bottom frame andfoundation board.

The body 1 comprises two side loading doors 76 and rear end loadingdoors 77 said doors standing vertically when closed and being locatedabove the top of the frustoyramidal portion of the booliy 1. The sidedoors 76 are xedly connecte to hi 78 having gears 79 thereon which meshwith other gears 80 on door operating shafts 81; the said shafts 81being operatively connected by gears 82 to an end door operating shaft83 operatively connected to the end door 77 in the same manner that theshafts 81 are operatively connected with the side doors 76. This insurestheV simultaneous opening and closing of the side and end doors.

In connection with each of the side and end doors, pivoted latches 84are provided, the same engaging keepers 85 on` the doors. The latches 84are operated by flexible connections 86 from two side latch operatingshafts 87 and an end latch operating shaft 88 as shown in Fig. 21, theshafts 87 and 88 being operatively connected by gears 89 forsimultaneous operation. One of theside shafts 81 is operated, as shownin Fi 18, by a Worm,shaft 90 journaled in the earing 91 on the body 1and having fast on its outer end a hand wheel carrying a handle 93. Oneof the latch operating shafts 87 has fast on the front end thereof anoperating lever or. crank arm 94 Within reach of the operator in hiscompartment, Who may thereby unlatch all of the loading doors, open saidloading doors, and again close and latch the same. either when the bodyis elevated or lowered. 95 designates one of a series of bearingbrackets for `the shafts'81 and 87, one of said brackets beingillustrated in detail in Figo 16 and the same being bolted to the body1.

96 designates a center board or division board, the same being removablyinserted between holding lugs 97 on the inside of the body 1 as shownfor example in Figs. 2 and 5. This center board 96 is arranged directlyover the division strip 3 of the bottom frame 2 and embodies a gateway98 in the bottom thereof which is controlled by a verticallyslidable-gate 99 movable in guides 100 on the board 96. The gate 99 isopened and closed by means of a hand lever 101 pivotally mounted at 102on the top edge of the board 96 and Mving a rack face 103 adapted ngerods" This may be accomplishedY to be engaged and held by a detent 104.The lever 101 is connected by a link 105 to a gate opening and closingrod 106 attached to the gate 99 at 107, Hand holes 108 are formed in theboard 96 to facilitate placing said board in position and removing thesame therefrom.

The foundation board 1.3, when in its lowered position, is yieldinglysupported by' weighing springs 109 in turn supported by the platform 15as shown in Fig. 1. The weighing mechanism comprises a stationary dial110, an indicating hand 111 carried by a rotatable arbor 112 actuated bya verti cally extending and movable rack bar-113. As shown in Fig. 6,the rack bar 113 cornprises a tubular extensible member 114 which isadjustable longitudinally 'of the rod or bar 113 by means of a set screw115. This enables the length of the actuating member of the weightregistering or indieating mechanism to be adjusted in length. Said rodor bar 113 passes through a lock box 116 the door of which is formedwith a key hole 117. After the door of the lock box has been locked,unauthorized persons are prevented from tampering With the adjustment ofthe register actuating member 113. In this way the proper official mayadjust the Weight registering mechanism and then lock and seal. thesaznc.

l/Vhen the Wagon is being driven from place to place, in order toprevent injury to the Weighing mechanism, the foundation board 13 issupported upon a plurality of riding blocks 118 which are hinged at 119tothe top platform 15. The blocks 118 are normally held in theirsupporting 'positions as shown in Figs. 1, 5 and 22 by means of springs120. Said blocks are moved away from their body supporting positions bymeans of flexible connections or cables 121 passing around pulleys 122,joined together at 123 and then extendin around other guide pulleys 124to a hand ever 125, which, as shown in Fig. 1 is mounted at one side ofthe drivers seat 126, said lever being of the thumb latch type as shownso that the riding blocks 118 may be held in their nonuseful positionduring the Weighing of the load. When the lever 125 is relaxed, thesprings 120 return the riding blocks to their useful positions.

From the foregoing description taken in connection with the accompanyingdrawings it -Will now be seen that We have produced a combination wagonby which the load may be weighed, theV vehicle may be disposed witheither side parallel to the curb, the body dumps from the bottom, delivers to chutes extending from either side or both sides, the body isself-emptying either in ani elevated or depressed position, the body maybe raised andlovvered by hand oi' by` motor, the outlet doors may bewespen operated from the seat or from the ground, separately orsimultaneously with the body `elevated or lowered. All of the loadingdoors may be operated simultaneously from the seat, the riding blocksmay be operated simultaneously from the seat, bags or other receptaclesmay be filled from the platform; the center board. allows for single ordouble delivery; coal or other material may be delivered to coal holesnear the curb or directly into wheel barro'vvs or the like, and theweighing register or indicator may be adjusted and thereafter locked andprotected.

The Weighted lower endsV of the hinge gears 7 9 helps to balance theloading doors as they are moved toward open and closed positions. Thebody cannot drop unless both elevating chains or cables breaksimultaneously. The center of gravity admits of a consideralile range ofinclination of the dump wagon while the body is partly or whollyelevated.
